SANFORD, Fla. -- A surveillance video shot after the slaying of Trayvon Martin shows admitted shooter George Zimmerman being led in handcuffs from a police car, frisked and led down a series of hallways.

Sanford police Sgt. David Morgenstern today confirmed that the video being shown by ABC News is of Zimmerman. The 28-year-old's head and face are visible throughout.

Zimmerman told police that he shot the 17-year-old Martin on Feb. 26 after Martin attacked him. His attorney has said Zimmerman's nose was broken in the fight and the back of his head was gashed.

A lawyer for Martin's family says the video clearly shows that Zimmerman's nose wasn't broken and he had no noticeable blood on his head and face.

Police did not arrest Zimmerman, touching off widespread public outrage and protests across the country.
